BetaFPV Cube 2-4S 30A AIO Flight Controller with ELRS 2.4GHz Receiver

The BETAFPV Cube 2-4S is a 3-in-1 AIO flight controller built for propulsion upgrades on 2-4S whoop and toothpick builds, combining an STM32G473 flight controller, a 30A continuous ESC and a built-in Serial ELRS 2.4GHz receiver on one compact board.

Key features

• 3-in-1 integration combines the FC, ESC and receiver on one board, cutting weight and wiring versus separate components.
• 30A continuous ESC (up from 20A on the earlier F405 board) with 2oz copper thickness handles the surge demands of aggressive 2-4S freestyle flying.
• Onboard Serial ExpressLRS 2.4GHz receiver removes the need for a separate RX module.
• UART4 drives an external HD digital VTX (DJI, Walksnail, HDZero), while two further full-featured UARTs are free for a GPS or other serial accessories.
• 168MHz STM32G473 MCU and an ICM42605 8kHz gyro give responsive handling for freestyle and cinematic flying.
